There are two factors that govern the selection of cable: the location of cable runs, either indoor or outdoor, and the maximum length of the individual cable runs. Video coaxial cable is designed to transmit maximum signaling energy from a 75 ohm source to a 75 ohm load with minimum signal loss. Excessive signal loss and reflection occurs if cable rated for other than 75 ohms is used. Cable characteristics are determined by a number of factors (core material, dielectric material and shield construction, among others) and must be carefully matched to the specific application. Moreover, the transmission characteristics of the cable will be influenced by the physical environment through which the cable is run and the method of installation. The preferred dielectric material is foam polyethylene. Foam polyethylene has better electrical characteristics and offers the best performance over solid polyethylene, but it is more vulnerable to moisture. Use cable with solid polyethylene dielectric in applications subject to moisture. Due to changes in fire and safety regulations throughout the country, Teflon and other fire-retardant materials are becoming more popular as outer-jacket and dielectric materials. In case of a fire, these materials do not give off the same poisonous fumes as PVC-type cables, and therefore, are considered safer.
A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (mechanical, chemical, solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source. Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from: Electrical energy transmission systems. Common examples of this include power supplies that convert AC line voltage to DC voltage. Energy storage devices such as batteries and fuel cells. Electromechanical systems such as generators and alternators. Solar power. A power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. Examples of the latter case include the low voltage DC power supplies that are part of desktop computers and consumer electronics devices. Commonly specified power supply attributes include: The amount of voltage and current it can supply to its load. How stable its output voltage or current is under varying line and load conditions. How long it can supply energy without refueling or recharging (applies to power supplies that employ portable energy sources).
NVR For CCTV Camera Distributor Price in Karachi, Pakistan is MB Communication What are NVRs and DVRs? NVRs (network video recorder) and DVRs (digital video recorder) are what you use to manage, view, and store surveillance videos. Available with a variety of software and hard drive sizes, NVRs and DVRs make it easy to save and review videos. Which one you need, and how it works, depends on having CCTV or IP surveillance cameras. How NVRs and DVRs Work NVRs and DVRs have the same job of saving and storing surveillance videos, but they are designed to work with different types of cameras. Both NVRs and DVRs come in form factors—stand alone appliance, a tower server, or a rackmount server. DVRs are used in CCTV, or analog, surveillance systems. Older systems would record video directly to tapes using a VCR; modern systems use DVRs to convert video files into digital formats, allowing you to store more videos. DVRs also give you the convenience of remote access, common on newer IP cameras and NVRs. If you have IP cameras, you’ll want a NVR instead. These recording devices use the local network to send and receive data, and are ideal for remotely monitoring your surveillance system from your computer, smart phone, or tablet. Because IP cameras are the cutting edge of surveillance technology, including a NVR in your system allows you to include new cameras with more advanced features. While most IP cameras and NVRs are compatible, you should always check with your surveillance system integrator to ensure all your products will work together properly. If your surveillance system has a mixture of CCTV and IP cameras, you can use specialized video encoders that allow your CCTV cameras to be connected to an NVR.
